Update
Low level ridge axis has shifted south of the region and extends
from the gomex across the fl peninsula and this has resulted in
steering flow out of the w/sw and will allow for even warmer max
temps into the mid/upper 80s inland today while the atlc coast sea
breeze front will be pinned to the i-95 corridor from jax
northward while reaching the st. Johns river basin south of jax
and this will allow the beaches to reach closer to 80 degrees.

Rain chances remain low along the sea breeze fronts today around
10% or less with only a slight chance of a shower/storm along the
ocmulgee and altamaha river basins of inland SE ga which is closer
to the mid level shortwave axis and old trof axis at the surface.

Tonight... Ridge remains in place south of the region as weak
frontal boundary approaches from the north across the SE u.S. And
this will lead to generally partly cloudy conditions and lows
still generally in the mid/upper 50s inland and lower 60s along
the coast. Main weather impact tonight will be potential for low
stratus/dense fog formation along the big bend region that may
track e/ne into the i-75 corridor of inland north florida towards
morning and low vsbys will be possible and the SREF probs of dense
fog are around 50% on the latest 09z run. The latest forecast
contains areas of fog in that region which will hold for now with
later updates can upgrade to areas of dense fog if hrrr starts to
come into better agreement with this scenario.

Aviation
Vfr through 09z tonight. Closer to sunrise Wed morning models are
coming into some agreement with low level stratus/fog developing
in the big bend region and pushing into the i-75 corridor which
may impact the kgnv TAF location in the 09-12z time frame and may
need to include potential ifr cigs/vsbys in the next TAF package.

Still low chances that the low cigs/vsbys reach the rest of NE fl
taf sites.

Marine
General southerly flow at 10-15 knots today become sely at the
coast with local sea breezes. Long period swells of 3-5 ft
nearshore and 4-6 ft offshore will continue with scec headlines
offshore. SW to W winds tonight at similar speeds as the swells
slowly start to decrease. Then light/variable flow Wed morning
will become onshore with local sea breezes by the afternoon.

Rip currents: moderate risk continues today in the long period
swells with morning breaker/surf reports in the 3-5 ft range.

Swells begin to fade tonight/early Wed in the offshore flow and
expect marginal moderate risk to linger on Wednesday.

Climate Record MAX temperatures may be challenged across
se ga both Wed and thu.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
